Scientists at Queen Mary, University of London have uncovered fundamental differences between the bone which makes up the skull and the bones in our limbs, which they believe could hold the key to tackling bone weakness and fractures.
It is well know that bones in the arms and legs become weak and vulnerable to breaks when they are not maintained by weight bearing exercise.
However skull bone, which bears almost no weight remains particularly resistant to breaking.
The new research offers an explanation for this phenomenon for the first time.
